Multiple vulnerabilities were discovered in roundcube, a skinnable AJAX based webmail solution for IMAP servers, which could result in account takeover, cross-site scripting, SSRF bypass, information disclosure or denial of service.

For the stable distribution (trixie), these problems have been fixed in version 1.6.17+dfsg-0+deb13u1.

We recommend that you upgrade your roundcube packages.
